SynergyBuild on Uh, is Chromium Lukka?

Femme_Fatale No it's definently a real bug, click on the link to the card page for Chromium, the Mutable, under it's type it's "Legendary Creature - Lukka".

mudkipdude on Uh, is Chromium Lukka?

I don't think he is, but I'm making a deck of cards that I want to get, purely on how much I like the cards (what is a synergy is the entire premise), and I go into subtype because WHY DO I HAVE SO MANY ARTIFACTS, I DIDN'T PUT 30 ARTIFACTS IN THIS, and I look at my elder dragon list, and there's Ancient Bronze Dragon, Ancient Bronze Dragon, Dragonlord Dromoka, Dragonlord Kolaghan, and Dragonlord Ojutai, but no Chromium, the Mutable. I go to find it, and it's under... Lukka? Also, might I add that I do not have a Lukka planeswalker in the deck. is it a glitch or... deck here:


shitballsman on What equipments work with Chromium?

i was wondering if equipment effects like Mask of Memory work when equipped to Chromium, the Mutable when its ability causing it to lose all abilities is activated (the equipment was already equipped in this scenario).

ANYTHING with Transmute. I know Muddle the Mixture is a well-known performer, but there are so many others that have good effects and double as toolbox tutors, especially in my Toluz, Clever Conductor deck where I can reuse them on a later turn.

Dimir Infiltrator in my Chromium, the Mutable Voltron is an all-star. In longer games it can serve as an attachment point for my spells, and it can tutor out Phyresis, Stoneforge Mystic, and so much more. It's incredible.

Anyway, as far as card suggestions go, you can't be guaranteed that your opponent will be running instants or sorceries, so a full playset of Test of Talents might be a bit much. Against token strategies, Detention Sphere or Temporary Lockdown could be good. Not sure I'm a fan of the plan for Ethersworn Adjudicator, but it could be a decent way to close out the game. You could reduce the number of creatures overall and go with a typical control finisher, such as Chromium, the Mutable or Hullbreaker Horror. In the same vein as Extirpate, Necromentia or Unmoored Ego could be useful. With the number of enchantments you have, Sphere of Safety might be a fun way to prevent combat. You may want to include a way to remove creatures if they do get any onto the field before you can pull them out of the deck, so Supreme Verdict, Settle the Wreckage, Day of Judgment, or similar.

Fun fact! Piru, the Volatile was actually the lover of Chromium, the Mutable. There were actually several other Elder Dragons native to Dominaria that have yet to be explored or really depicted in cards such as Marrevia, Ravus, Rubra, and Lividus. They are cousins of Vaevictis Asmadi, the Dire!

Anyways, Lore aside, here's my interpretation of Marrevia!

Marrevia-Sal, the Despised

Legendary Creature - Elder Dragon


At the beginning of your upkeep, sacrifice ~ unless you pay .

At the beginning of your endstep, you may pay X life. If you do, mill that many cards, then return a creature card from among cards milled this way to the battlefield. If it were to leave the battlefield, exile it.

Stern Dismissal I wouldn't bother playing too many of. That's highly situational, and could help you get lethal damage through by bouncing a critter. It's also not a counterspell. In a similar vein, Essence Scatter is useless if you're going up against a control player (who play very few, if any creatures, and the ones they do play usually come with the "Can't be countered" ability). See Chromium, the Mutable, Hullbreaker Horror, etc. If your meta is creature heavy, then by all means. Though I do have a preference for counterspells that exile instead of having the spell hit the graveyard. Ertai's Scorn is really useful in matchups against burn, or against fast aggro decks, but again is situational. If Lilly is your bane, then you could consider Negate which is effective against walkers for 2 CMC.

Palladia-Mors and Palladia-Mors, the Ruiner are the worst Elder Dragons, imo. I want her to get better representation...

Palladia-Mors, the Hunter

Legendary Creature - Mors

+2: Palladia-Mors, the Hunter deals 5 damage to target creature or planeswalker. Excess damage is dealt to that permanent's controller instead.

-5: Choose a permanent type. Each player chooses a number they control equal to the number controlled by the player who controls the fewest permanents of that type, then sacrifices the rest.

-14: Creatures you control gain lifelink and indestructible. Each creature deals damage equal to its power to each other creature.

Palladia-Mors, the Hunter can be your Commander


I'd like to see one of the three other Original Elder Dragons made into a Planeswalker-Commander:

Arcades Sabboth / Arcades, the Strategist

Chromium Rhuell / Chromium, the Mutable

Vaevictis Asmadi / Vaevictis Asmadi, the Dire
